Naomi has a suggestion for the Spiral Pop-Up Card: "I put a little spin on the one I just did. I made the spiral out of acetate on a black Halloween card, Jack-o-lanterns pop up, and for a minute, you can't tell how, since the spiral is clear! I will have to post a picture soon. I just wanted to share the idea of doing it with acetate. Thanks so much for a great tutorial."
